→Arduino Nano

according to https://www.arduino.cc/en/Guide/Introduction: Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board.

Neuron Power Engineer supports Arduino Nano 3.
The tutorial "Putting Controllino or Arduino Nano into operation" describes how to put an Arduino Nano into operation as well as load a sample application created in Neuron Power Engineer onto the Arduino Nano.
